Definitions

  • This invention relates to toy aeroplanes, and contemplates, among other things, :the provision of a source of motive power entirely outside of the plane for rotating the coax ially mounted propellers.
  • the motor has usually been carried by the plane itself, and has taken various forms which add materiallv to the Weight of the plane.
  • My in vention includes the provision of a distant source of power not carried by the plane, but
  • the invention contemplates .further improvements in the art of flying aeroplanes including control thereof from terra firma and allowing continuous flight for an unlimited period and at any desired speed whilethe operator is enabled to reverse the action of the driving mechanism to show the plane up and to reverse the direction of flight, if desired;

  • Fig. 2 is a partial'verticalsection and side view of a part of the plane and of the driv-.
  • Fig. 3 is an enlarged vertical section of the coupling which connects the flexible cable with the driving mechanism of the plane and with the source of power.
  • Fig. 4 is a top plan view of the same.
  • Fig. 5 is a front view and partial vertical 1- posed form of the motive power.
  • Fig. 6 is a vertical section of the same, taken on theline 66 of Fig. 5.
  • Oneof th'e' propellers 10 is mounted on one end o'f-the shaft 11in the usual manner, said shaft being suitably j our ⁇ nailed near the other end thereof'in thepartition "14L.
  • the teeth 17 ,of'said spur gear enter the: perforations 18 of the gear 16 whereby rota;v tion of the perforated gear will cause rotation of the propeller 10.

  • hollow propeller shaft 111 in the usual man-1 ner as by means of the nut-100 and the bushmg 101, said shaft being supported the head 12 of the fuselage13 and by the solid propeller shaft 11.
  • shaft 111 is similar in allf respects to that i for the shaft 11 and consists of the spur gear 115 and the perforated gear 116 preferably identical with the gears 15 and 16 respective-.
  • the supports for the perforated gears and A the couplings which operatively connejctsaid gears to the flexible drive shafts areprefer ably identical, so that only one of the sup Y ports and couplings need be described.
  • Each of the perforatedgears ismounted on a shaft l9 passingthrough the bearing 20. Near the lower end of the shaft-19 as at 21, is a pin 22 projecting outside thereof to form an anchor for the coupling29.
  • the bearing 20 isse cured at the upper end23 thereof to the swingable frame 24 which is preferably U shaped, having upstanding arms 25 and 26 engaging and pivotally mounted" on the shafts 111 and 11 respectively.
  • the lower end 27 of the bearing 20 is externally threaded and has an opening 28 therein of suitable size to receive the coupling 29.
  • Rotation of the shafts 19 is effected by means of flexibles'hafts as 30 and 31 of thin music wire or-the like.
  • Each of said shafts passes through a bushing 32into the interior of the hollow coupling 29.
  • the end 33 of eachof the flexible shafts is bent at substantially right angles to the remainder and .is 9
  • V 7 plane When the V 7 plane isin full'flight, it'may be pulled by the L N flexible shafts toward the operator who would usually stand toward one side" of the I plane; The flexible shafts, therefore, tend to W pull the gears 16and the shafts 1 8'on which they are mounted, together with itheframe.

  • crank 43 may be replaced by an automatic source of power such'as a motor provided with suitable' controls if desired.
  • crank48 is merelyturned faster, and should it be desired to cause the plane to perform the usual acrobatic tricks, rotation of the crank is slowedorstopped, thereby lessening or cutting off the power a and sending the plane into a nose dive from which it may be righted into normal flyingposition by again rotating the crank and imparting forward movement to the plane.
  • the plane may be caused to perform other tricks. Itmay be brought to the ground gradually and caused to alight'in simulation of the action of a full sized plane by gradually reducing. the speed of rotation of the propeller.
